In these days, there is a growing expectations for the possibility of the unification of South and North Korea and measures in terms of supply and demand of infrastructure services are increasingly needed. In particular, it is highly expected that shortage of housing infrastructure services will be the most critical problems right after the unification. This study thus proposes modular construction to build apartment houses to prepare for massive population movements after Korea unification. The size of the modular was determined considering supply chains as well as legal aspects such as the minimum residential area. Two housing sizes were set considering the unification migrants, and unit plans were designed. After calculating the information such as the quantity of major materials by BIM, the alternatives were compared and analyzed in various viewpoints. This study can be used as a basic study on apartment housing after unification.

The fast neutron rates are compared at the site of the NEOS (Neutrino Experiment Oscillation Short baseline) experiment, a short-baseline neutrino experiment located in a tendon gallery of a commercial nuclear power plant using a 0.78-liter liquid scintillator detector. A pulse shape discrimination technique is used to identify neutron signals. The measurements are performed during the nuclear reactor-on and -off periods, and the fast neutron rates are found to be consistent with each other. The fast neutron rate is also measured at an overground site with a negligible overburden and is found to be ∼ 100 times higher than that at the site of the NEOS experiment.
Seesaw Scale and CP Phases in a Minimal Model of Leptogenesis
Kim Siyeon 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.69 No.11
The seesaw mechanism to derive the light masses of left-handed neutrinos using heavy masses of right-handed neutrinos gives rise to a connection between low-energy measurables and Grand Unified Theory (GUT)-scale mechanism. We express the neutrino mixing angles in terms of a single variable sin θ13, whose size was measured recently. The lepton asymmetry from the decays of heavy neutrinos via Yukawa coupling is described by CP phases in both Dirac and Majorana type. It is shown that the seesaw scale relevant to the lepton asymmetry can be constrained by CP phase in this minimal model.

<P>The purpose of this study was to examine the frequency of firefighters’ heat-related illness (HRI) in the line of duty with relation to resting/working hours and the behaviour of taking off PPE during rest periods based on nationwide survey (N=674). The results showed that 74.8% of firefighters experienced HRI symptoms and 5% of firefighters suffered from symptoms of HRI 20 times or more in a year. This study also showed a statistically significant correlation between working hours and removing PPE with the experience of HRI symptoms (<I>p</I><0.05). In addition, removing PPE except the helmet was correlated with resting hours (<I>p</I><0.001; Gloves: <I>p</I>=0.051), which indicates that removing PPE is related to resting time. This study revealed that firefighters routinely experienced mild HRI symptoms and the fatalities were just a tiny fraction. It is also emphasized that attention should be given on the significant role of taking off PPE during rest and on the standardized firefighters’ rehabilitation followed by its application.</P>
Re-Visioning of the “Universal” in Adrienne Rich’s Poetry
Siyeon Kim Ewha Institute of English and American Studies 2023 Journal of English and American studies Vol.21 No.2
Literary critics have long acknowledged that Adrienne Rich’s poetic style changes from being self-effacing to woman-identified. This paper traces the development of Rich’s poetry through “Snapshots of a Daughter-in-Law” and “Diving into the Wreck,” which are both poems about the reality of women’s lives. The shift in Rich’s style of writing shows how she embarks on a feminist journey to find a new “universal” language that conveys the experiences of men and women alike. “Snapshots of a Daughter-in-Law” could be seen as an early yet incomplete attempt at using this “universal” language; the division between Rich and her female characters, as well as her reliance on allusion, reveal that Rich was still under the influence of male poets. However, over the years, Rich overcomes these shortcomings and succeeds in moving towards a feminist poetics. In addition to feminism, Rich’s thematic concerns come to include queer theory, which can be observed in “Diving into the Wreck.” By comparing two works from different points in Rich’s poetic career, this paper illuminates how Rich struggled to include women and queer groups in the male-dominated world of literature.

This retrospective cohort study aimed to compare coronavirus disease 2019 (COVID-19)- related clinical outcomes between patients with and without gout. Electronic health recordbased data from two centers (Seoul National University Hospital [SNUH] and Boramae Medical Center [BMC]), from January 2021 to April 2022, were mapped to a common data model. Patients with and without gout were matched using a large-scale propensityscore algorithm based on population-level estimation methods. At the SNUH, the risk for COVID-19 diagnosis was not significantly different between patients with and without gout (hazard ratio [HR], 1.07; 95% confidence interval [CI], 0.59–1.84). Within 30 days after COVID-19 diagnosis, no significant difference was observed in terms of hospitalization (HR, 0.57; 95% CI, 0.03–3.90), severe outcomes (HR, 2.90; 95% CI, 0.54–13.71), or mortality (HR, 1.35; 95% CI, 0.06–16.24). Similar results were obtained from the BMC database, suggesting that gout does not increase the risk for COVID-19 diagnosis or severe outcomes.
Cooling performance measurements of different types of cooling vests using thermal manikin
Siyeon Kim,Seojin Lee,Sora Shin,Daeyoung Lim 한국의류학회 2024 Fashion and Textiles Vol.11 No.1
This study compared the effectiveness of five commercially available cooling vests using three distinct thermal manikin test protocols. In addition, the constraints associated with each test protocol were elucidated, facilitating the identification of suitable evaluation methods for the different cooling vests. The cooling performances of the vests were evaluated using three thermal manikin test scenarios, incorporating the adaptations from Ciuha et al. (Ergonomics 64:625–639, 2021) and ASTM F2371-16, along with a modified protocol simulating the hot and humid weather in a South Korean summer. The results revealed substantial variations in the cooling performance across different test protocols, highlighting the importance of carefully selecting thermal manikin test methods. Moreover, the specific cooling vests exhibited immeasurable performance in certain test methods, which presents the limitations inherent in each testing scenario. For example, when evaluated with a non-sweating thermal manikin, the air-cooling vests exhibited the worst cooling performance, showing an average cooling rate of 1.0 W and cooling durations of five minutes. In contrast, the same vests demonstrated superior performance when assessed using the ASTM F2371-16 method, revealing an effective cooling rate of 114.8 W and sustained cooling durations exceeding eight hours. These results emphasize the lack of a one-size-fits-all evaluation method for cooling vests and the need for accessible guidelines to inform decision-makers aiming to enhance workplace safety and comfort.
